i have a eg hatch with ctr swap on a cold moring it strugles to stay running for about five min it will die at least 3 times after about five min of running its fine doesnt do this when warm.
2. is it possable to have bad o2 sensor and computer not read. when its warm out i get about 200 mpt i have noticeed when its cooler i get about 250 mpt does the o2 have anything to do with this both times is using no vtech

 

i wish i knew the answer have a very similar problem

 

at the gas station today turned car off went to get it wouldnt start seems to be idiling better when cold after i changed the plug wires back to 11 mm instead of stock?

 

again to day at the gas station the car hesitated to start i turned the key about ten times before the ecu decided it wanted to work could this be a dirty ecu maybe when i first got it it sat on a self and didnt want to work till i got it cleaned. the coms not sitting behind carpet or anything really to protect it just mounted to the inside of firewall could this be the same problem?
